How are you measuring your flour?
When I first started making bread it was heavy or too dry and not so nice. Turned out measuring flour by volume(as in with your standard dry measuring cups) can be inaccurate. Turned out with cups I was using almost twice as much as I should have. I got a kitchen scale and measured by flour by weight, using the proper amount of flour I have had no further problems. Although on warm or dry days I add a teaspoon or two more water...it seems to help.
